What are the materials of LED street light poles?LED street lights are more and more widely used in the lighting and decoration of wide roads such as urban roads, rural roads, and factory areas. Among them, the pole of the LED street lamp is very important to the street lamp, which directly affects the service life of the street lamp. The material of the pole is particularly critical. Today, CHZ lighting will give you an analysis of the materials of LED street light poles.
1. Cement light pole
Cement street light poles are attached to urban power poles or erected separately. This street light pole was commonly used many years ago. The disadvantage is that it is very heavy, difficult to install, has no recycling value, and is more dangerous than other materials. It has almost been eliminated by the market now.
2. Iron poleIron pole,
also called Q235 steel pole. It is made of high-quality Q235 steel, hot-dip galvanized and sprayed with plastic. It can be rust-free for 30 years and is very hard. The disadvantages are heavyweight, high transportation and installation costs, and low recycling value. Plug-in installation is not allowed. This is the most common and used street light pole in the LED street light market.
3. Fiberglass light pole
FRP light pole is a kind of inorganic non-metallic material with excellent performance. It has a wide variety of advantages. The advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, and light weight. It can be installed in a plug-in manner. However, the disadvantages are brittleness, poor wear resistance, short lifespan, very serious damage to the rod body by ultraviolet rays, easy to be damaged by external equipment, high maintenance costs and no recycling value, and processing is very difficult and expensive. Therefore, not many LED street lights are used in the market.
4. Aluminum alloy light pole
At present, aluminum alloy light poles (English name: Aluminum Light Pole) are mainly divided into two types, one is the casting aluminum method, and the other is the spinning method. Due to technological limitations, cast aluminum poles are generally less than 3 meters in height, and are usually only used as courtyard poles. Spinning light poles are high-speed spinning of 6061 or 6063 aluminum alloy pipes with equal diameters using large-scale numerical control equipment to form cones or special-shaped poles. The aluminum alloy street light pole has good anti-corrosion performance, maintenance-free, light weight, convenient transportation and installation, rich surface treatment, long service life, 100% recycling, energy saving and emission reduction; plug-in installation, strong wind resistance and small amplitude. The disadvantage is that the material cost is more expensive than other materials. Most of this LED street light poles are sold overseas, especially in developed countries.
5. Stainless steel street light pole
Stainless steel poles have the best chemical and electrochemical corrosion resistance in steel, second only to titanium alloys. The method adopted in our country is to carry out hot-dip galvanizing surface treatment, and the product life of hot-dip galvanizing in line with international standards can reach 15 years. Otherwise, it is far from reach. Mostly used in courtyards, communities, parks and other places. Heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance.
Light poles of different materials have their advantages and disadvantages. The choice of light pole material should be selected according to the actual situation.
